Peninsula Metal Finishing, Inc. has 22,000 square feet available for its operations. This enables us to accommodate current markets, and to react quickly to accept new opportunities that are presented.

Plating Capabilities

Expertise of owners, management, and associates, physical plant size, and plating process tank sizes, typically defines individual production capabilities.

The management team at Peninsula Finishing has extensive metal finishing training and job shop experience and establishes priorities of quality through process control, along with environmental stewardship. This philosophy insures that we offer our plating services as a responsible vendor and have the capability to provide current finishing requirements, as well as provide for unique opportunities in the future.

Our success is due to the ability to evaluate new metal finishing opportunities with our customers, establish quality and production criteria, engineer the process equipment and production methods that will meet that criteria, and then produce in a consistent and dependable manner.

In the event your finishing requirement is not listed in our Plating Process Capabilities, please call or e-mail us to discuss your parts. We are pleased to assist you in finding a source for your finishing.

Peninsula Metal Finishing's Operational Principles

The Process:

Metal finishing encompasses a variety of processes that can treat the base metal, such as passivation of stainless steels, or apply one or more coatings on the surface to perform a sacrificial function when exposed to the environment, to meet an engineering requirement, to perform a cosmetic function, or a combination of some or all of these. Additionally, pre-treatments for painting are also within the domain of metal finishing.

Most metals when left in their original condition will react with oxygen and other components of the environment and form oxides such as common rust on steels and white corrosion on aluminum. Additionally, metals generally do not possess the desired properties for the end product, from either an engineering or cosmetic perspective.

• Plating includes electro-plating, electroless plating, immersion coatings, conversion coatings, and mechanically applied finishes.
• Anodizing is unique in that a controlled oxide is formed at the surface of the aluminum.
• Painting and powder coating are non-metallic coatings.

THE TYPICAL ELECTROPLATING PROCESS INCLUDES:

• Removing oils and other contaminants from the surface of the part.
• Removing oxides from the surface of the metal.
• Plating the desired metal such as nickel or zinc utilizing direct current, or an electroless method, to deposit metal on the surface, or an immersion method to deposit a coating such as chemical film or phosphate.
• Baking for hydrogen embrittlement relief if required.
• Applying a supplementary coating to the plating.
